The sfaI determinant encoding the
S-fimbrial adhesin of uropathogenic Escherichia coli
strains was found to be located on a pathogenicity island of
uropathogenic E. coli strain 536. This pathogenicity
island, designated PAI III536, is located at 5.6 min of the
E. coli chromosome and covers a region of at least 37 kb
between the tRNA locus thrW and yagU. As far as
it has been determined, PAI III536 also contains genes
which code for components of a putative enterochelin siderophore system
of E. coli and Salmonella spp. as well as for
colicin V immunity. Several intact or nonfunctional mobility genes of
bacteriophages and insertion sequence elements such as transposases and
integrases are present on PAI III536. The presence of known
PAI III536 sequences has been investigated in several
wild-type E. coli isolates. The results demonstrate that
the determinants of the members of the S-family of fimbrial adhesins
may be located on a common pathogenicity island which, in E. coli strain 536, replaces a 40-kb DNA region which represents an
E. coli K-12-specific genomic island.
